LUETZERATH (Ger-many): Climate campaigner Greta Thunberg was detained alongside a group of activists on Tuesday during protests against the demolition of the coal village of Luetzerath, according to police.

A spokesperson for the police division in the region said it was not yet clear what would happen to Thunberg, who joined protesters at the site last week to campaign against the expansion of the mine, owned by energy giant RWE.

Riot police backed by bulldozers removed activists from buildings in the village with only a few left in trees and an underground tunnel by last weekend, but protesters including Thunberg remained at the site staging a sit-in into Tuesday.

Thunberg was detained while protesting at the opencast coal mine of Garzweiler 2, some 9 kilometres (5.6 miles) from Luetzerath, where she sat with a group of protesters near the edge of the mine.
